He continues: "While some common APA formatting errors may be issues due to changes in updated guidelines (APA 5 vs. APA 6), there are other, perhaps more common instances where a student fails to properly reference the source materials within writing assignments. This is particularly true when citing content from the Internet. Understanding how to properly reference and cite source materials adds power to any student paper, because the papers can be used to show a proper understanding and blending of source ideas - a critical concept in higher learning."
